Gr 4-6–Sophie has been living with her loving guardian, Charles Maxim, for almost all of her 12 years, ever since she was rescued as a baby from a floating cello case after a shipwreck. Charles reads Shakespeare aloud to her, serves her roast potato chips on an open atlas (owing to her penchant for breaking plates), and allows her to wear pants. In this 19th-century world, the Dickensian Miss Eliot, of the National Childcare Agency, decides that Charles is an unfit guardian and that Sophie must become a ward of the state. She and Charles escape to Paris, and it is there that Sophie begins her search for her mother, who, she is convinced, is alive after all and not drowned. Confined for security reasons to an attic room, she begins to explore the rooftops and meets an extraordinary boy, Matteo, who lives and scavenges entirely on the roofs. Life up there is full of dangers, and Sophie’s determination to find her mother lands her in some tough situations. Ultimately, however, with the help of Matteo and Charles, her quest comes to a genuinely touching and satisfying conclusion. Rundell’s gentle poetic style gives Sophie’s story a full-heartedness that makes it take flight at times and sweeps readers along with it. In describing Charles, Rundell writes: “Think of nighttime with a speaking voice. Or think how moonlight might talk, or think of ink, if ink had vocal chords.” Realistic fiction with the feel of fantasy, this atmospheric novel will appeal to a wide range of middle-grade readers.–Sue Giffard, Ethical Culture Fieldston School, New York City
